Copy/pasting the same code is redundant and updating copy/pasted code slows development velocity. Mixins is reusable chunks of code that is included, similar to calling a function, instead of copy/pasted.Mixins has some nice features:-Arguments just like functions.-Arguments can have default values and optional values.-Named arguments allow us to use optional and default arguments when the Mixin is included.-Variable arguments allow us to has a dynami
Brief Introduction to SCSS and brief introduction to scss
I. background:
Css is not a real programming language. It does not have the variables, loops, traversal, inheritance, and other features of programming languages.
To solve these shortcomings of css, the "Intermediate Language" that can pre-process css is generated to implement some programming features.
That is, in the process of compiling interm

Vue componentThe REM () inside is a scss function defined in the _FUNCTIONS.SCSS.@function REM ($px) { @return ($px/40px) * 1REM;}However, this REM () function has not been used, looking for a problem for a long time, of course,
Tired of dealing with monolithic CSS files? is requests for multiple CSS files hurting your performance? In this lesson we learn how to separate our styles with SCSS partials, and how SCSS imports compile to one file so there ' s Only one request.Things to know:
If importing partial file, won ' t generate a new CSS file
If importing normal scss file,
;margin-left:10px;} Use the @include command to invoke this mixin. div {@include left;} The power of mixin is that you can specify parameters and default values. @mixin Left ($value: 10px) {float: Left;margin-Right: $value;} When used, add parameters as needed: div {@include left (20px);} The following is an example of a mixi
We can use JavaScript for color and opacity variations, math, list and map logic or to see if something exists. SCSS includes functions for a wide range of common use cases for logic in our styles. In this lesson we look at some of the + useful color functions to improve development velocity, readability, and simpli FY the code. Be sure to checkout all the SCSS functions:http://sass-lang.com/documentation/s

First, explain the difference between sass and SCSS.1, similarities and differences: 1) In short, you can understand that SCSS is an upgraded version of Sass, fully compatible with the functions of sass, and some new capabilities. Grammatical forms are slightly different, the main thing is that sass is indented to represent nested relationships, scss is curly bra

The auth module implements OpenID and OAuth. Why does it use the Mixin method? What are the application scenarios of
